Abstract: | Udang vaname merupakan produk utama budidaya perikanan dan juga berisiko terserang penyakit AHPND (Acute Hepatopancreatic Necrosis Diseases) yang disebabkan oleh Vibrio parahaemolyticus. Salah satu alternatif untuk mencegah infeksi bakteri yaitu dengan menggunakan selenium organik. Tujuan penelitian ini untuk menganalisis pengaruh selenium organik dengan dosis berbeda melalui pakan terhadap kinerja produksi dan respons imun udang vaname yang diinfeksi V. parahaemolyticus. Udang yang digunakan memiliki bobot awal 5,64±0,18 g yang dipelihara selama 30 hari dan diuji tantang dengan V. parahaemolyticus dengan dosis 105 CFU/ekor pada hari ke-31 setelah diberikan pakan uji coba, kemudian mortalitas diamati selama tujuh hari. Perlakuan yang diberikan yaitu 2, 6, 12, 18 mg/kg pakan, dan kontrol tanpa selenium organik. Pemberian selenium organik mampu meningkatkan kinerja produksi dan respons imun udang terhadap infeksi V. parahaemolyticus. Dosis terbaik diperoleh pada 2
mg/kg pakan yang mampu meningkatkan laju pertumbuhan harian, laju pertumbuhan spesifik, rasio konversi pakan, dan melindungi udang terhadap infeksi V. parahaemolyticus. Pacific white leg shrimp is the main product of aquaculture and is also at risk of AHPND (Acute Hepatopancreatic Necrosis Diseases) caused by Vibrio parahaemolyticus. One alternative to prevent bacterial infection is to use organic selenium. The purpose of this study was to analyze the effect of organic selenium with different doses through feed on the production performance and immune response of shrimp infected with V. parahaemolyticus. The shrimp used had an initial weight of 5.64±0.18 g which was reared for 30 days and challenged by injection of V. parahaemolyticus at a dose of 105 CFU/shrimp on day 31st after given feed trials, then the mortality was monitored during seven days. The treatment given was 2, 6, 12, 18 mg/kg feed, respectively, and control without selenium organic. Administration of organic selenium was able to increase production performance and immune response of shrimp against V. parahaemolyticus infection. The best dose was obtained at 2 mg/kg feed which was able to increase the daily growth rate, specific growth rate, feed conversion ratio, and protect shrimp against V. parahaemolyticus infection. |
